CookieTin — Cookie Manager 作者： Perruer

CookieTin shows every cookie your browser keeps and lets you change it: in normal and private windows, in Multi-Account Containers, and the partitioned cookies that Total Cookie Protection keeps for embedded sites — the ones many cookie managers can't see or delete.

TOOLBAR MENU FOR THE CURRENT SITE
• Open the site's cookies in the manager
• Delete them, including subdomains and the cookies of embedded sites — with Undo
• Clear the site's localStorage, sessionStorage, IndexedDB and cache
• Delete all cookies of the window or container (asks twice; can be hidden)

MANAGER
• Domains, cookies and an editor side by side
• Search: github name:session value:abc
• Select several cookies (Ctrl/Shift or checkboxes) and delete, protect, export or copy them to another container at once
• Filters: session, protected, partitioned, HttpOnly, not Secure
• Live updates, keyboard shortcuts, dark theme

EDITOR
Every attribute: name, value, domain and subdomains, path, expiry or session, Secure, HttpOnly, SameSite, container, partition, first-party domain. URL and Base64 decode/encode, JSON Web Token decoding, byte size, and a warning when the browser would reject the cookie.

PROTECTED COOKIES
Lock the cookies that keep you logged in. CookieTin never deletes them and can restore them when a site or the browser removes them.

AUTOMATIC CLEANUP
Delete unprotected cookies when Firefox starts and/or every 1–24 hours, keeping the sites open in your tabs.

IMPORT & EXPORT
JSON (compatible with Cookie-Editor and EditThisCookie), cookies.txt for curl, wget and yt-dlp, a Cookie header line, Cookie Quick Manager JSON; import from Playwright/Puppeteer too.

COMING FROM COOKIE QUICK MANAGER?
CookieTin is a maintained rewrite of it. In Cookie Quick Manager's settings click "Backup user data", then "Restore from file…" in CookieTin: your protected cookies and settings come along.

PRIVACY
No accounts, no analytics, no network requests. Everything stays in your browser.

English, Russian, German and French interface. Works on Firefox for Android too.

CookieTin is free and open source (GPL-3.0), based on Cookie Quick Manager by Ysard.
